Additional question - I have to convert the numbers as the value of the RSSI is in dB, how do i print out the values rather than just the formula:
Code:
#!/usr/bin/expect -f
set timeout 8
log_user 0
set ip [lindex $argv 0]
spawn -noecho telnet $ip
sleep 2
set count 0
set result 0
set value 0
set resultDb 0
send "PS1='PROMPT# '\r"
expect -re "PROMPT# '(.*)PROMPT# "
while {$count < 20} {
send "iwconfig wlan0 | grep -o \"Signal level=....\" | cut -c14-16\r"
expect -re "\r\n(.*)\r\n(.*)PROMPT# "
set valdB $expect_out(1,string)
set value 10^($valdB/10)
set result [expr $result+$value ]
set count [expr $count+1 ]
}
send "exit\r"
expect eof
set result [expr $result/20 ]
set resultdB 10*log(($result/10)/log(10))
puts "Average RSSI $resultdB"
Hello Experts,
Happy New Year to all of us,

Hello,
I have AIX 5.3 at home connected to netgear router. Port Forwarding has been enabled on the router. Problem is that if I want to telnet, I have to try 2 or 3 times before I can get a logon prompt. It times out for first or second time (Connection to session <IP_Address> failed: Connection... (1 Reply)
How can I disconnect an existing telnet session? The host is a serial port server with multiple ports. The users login using the host's name and a port, i.e. telnet host01 1235.
Thanks. (14 Replies)
Our network administrators implemented some sort of check to kill idle sessions and now burden is on us to run some sort of keep alive. Client based keep alive doesn't do a very good job. I have same issue with ssh. Does solution 2 provided above apply for ssh sessions also? (1 Reply)
Hi,
I'm trying to spawn a telnet process and trying to do some actions in the remote host using expect script. I would like to know how to suppress all the output in order the user using the script should not be able to see any actions done on the remote host. I tried using the "log_user 0"... (8 Replies)

telnet-probe
TELNET-PROBE(1) General Commands Manual TELNET-PROBE(1)NAME
telnet-probe - lightweight telnet-like port probe
SYNOPSIS
$PCP_BINADM_DIR/telnet-probe [-c] [-v] host port
DESCRIPTION
telnet-probe allows the pmdashping(1) daemons to establish connections to arbitrary local and remote service-providing daemons so that
response time and service availability information can be obtained.
The required host and port number arguments have the same meaning as their telnet(1) equivalents.
The -c option causes telnet-probe to perform a connect(2) only. This skips the read(2) and write(2) exercise that would otherwise be done
after connecting (see below).
The -v option causes telnet-probe to be verbose while operating.
Once the telnet connection has been established, telnet-probe reads from stdin until end-of-file, and writes all the input data to the tel-
net connection. Next, telnet-probe will read from the telnet connection until end-of-file, discarding whatever data it receives. Then
telnet-probe exits.
To operate successfully, the input passed via telnet-probe to the remote service must be sufficient to cause the remote service to close
the connection when the last line of input has been processed, e.g. ending with ``quit'' when probing SMTP on port 25.
By default telnet-probe will not produce any output, unless there is an error in which case a diagnostic message can be displayed (in ver-
bose mode only) and the exit status will be non-zero indicating a failure.
PCP ENVIRONMENT
Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. On each installation, the
file /etc/pcp.conf contains the local values for these variables. The $PCP_CONF variable may be used to specify an alternative configura-
tion file, as described in pcp.conf(5).
DIAGNOSTICS
If telnet-probe succeeds, then 0 will be returned. If the attempt to establish a connection fails or is terminated, then a non-zero exit
status is returned.
